'96 850T, 145k miles. CEL light came on today, code P0422 (five minutes before I entered testing garage for emissions test - bummer).

Purchased online...repairs postponed until tool arrives.

Does anybody know where I can locally (Portland, OR) buy/rent/borrow a Schley 91400B Universal Overhead Valve Spring Compressor (or equivalent) tool?
